The Suzuki Motorcycle DR650S headlight bulb uses a 9003 size for both high beam and low beam functions. The replacement chart covers vehicle production years spanning 1990 to 2019.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Suzuki Motorcycle DR650S uses the 9003 bulb size for both high beam and low beam headlight positions across all model years listed in the specifications, spanning 1990-1993 and 2007-2019.
The 9003 is an ANSI-standardized bulb type recognized in the United States and Canada, meaning its physical and electrical characteristics conform to a defined industry standard rather than varying by manufacturer.
The 9003 bulb is a dual-filament halogen type, which allows a single bulb unit to serve both the high beam and low beam functions through two separate internal filaments operating at different wattages.
The bulb operates on a 12-volt electrical system and draws 60 watts on the high beam filament and 55 watts on the low beam filament, reflecting the standard output ratings for this bulb type.
The 9003 uses a P43t base, which is a bayonet-style mount with a 43mm flange. This base type determines physical fitment into the headlight housing and is not interchangeable with other base configurations.
The 9003 and H4 bulbs share the same dual-filament halogen design, P43t base, and 60W/55W ratings, making them functionally equivalent. However, 9003 is the ANSI designation while H4 is the ECE designation used in international markets, and substitution should be confirmed against the housing before use.
Because both the high beam and low beam positions call for the same 9003 bulb across all listed model years, a single replacement bulb type covers both functions on the DR650S.
